CUSPlDOR.

SPECIFICATION forming part of Letters Patent N'oi 721,os dated February17, 1903.

Application filed April :11, 1602 Serial in, 102,402 (No model.)

To. all whom it mayconoern;

Be it known that 1, CHARLES A. PAYNE, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Cuspidors, of which the following, taken in connectionwith the accompanying drawings, is a full, clear, and exact description.a

This invention relates to improvements in cuspidors, having moreparticular reference to lids or removable tops adapted to contain adisinfectant or deodorizing fluid.

The object of my invention is to produce a removable hollow top or lidfor cupidors adapted to contain a liquid disinfectant .or deodorizer andto discharge the same through a restricted passage or passages into themain receptacle.

Another object .is' to provide the hollow shell with suitable inlet andvent openings, whereby the chamber for the disinfectant may be readilyrefilled when desired.

Another object is to provide a valve for the discharge-opening forcontrolling the discharge of the disinfectant.

To this end the invention consists in th combination, construction, andarrangement of the parts of a cuspidor top or lid, as hereinafter fullydescribed, and pointed out in the claims.

Referring to the drawings, Figure 1 is a transverse vertical sectionalview of a cuspidor provided with myimproved lid, which is also shown insection. 2 Fig. 2 is an inverted perspective view of the detached lid ortop. Fig. 3 is an enlarged sectional view of the cap or plug for theinlet and the valve for controlling the outlet. Fig. 4 is an enlargedper spective view of the detached valve.

Similar reference characters indicate cor-.

responding partsin all the views.

In the drawings I have showna cuspidor consisting of a main receptacle 1and a removable cap '2. The receptacle 1 may be of any desiredconstruction, the lid 2 being made to conform tothe shape of the mainreceptacle. These receptacles are generally circular in top plan, and Ihave shown a circular lid 2, consisting of a hollow shell having acentral opening 3 and outer and inner shells 4 and 5, having portionsthereof arranged in separated relation to each other for forming achamber 6, containing a liquid disinfectant. This chamber Gpreferablysurrounds the opening 3 and is provided with an inlet-opening 7 and anoutlet-opening 8, leading from the chamber through the inner wall of theshell, the outlet-opening communicating'with the interio'r' of the mainreceptacle when the lid is in operative position. The inlet-opening maybe at any convenient position in either of the walls of the shell; butin order to prevent any tampering with the inlet I preferably arrangethe same in the inner wall 7 and provide a suitable cap 9 for closingthe same. As seen in the drawings, this inlet-opening is threaded andthe'cap 9 is also threaded, which forms a convenient means for closingthe inlet and holding the cap in position.-

In order to provide for the displacement of air from the chamber 6 whenthe shell is being filled, I provide a vent-opening 10, which may belocated at any convenient position sufficiently above the base of theinner wall 5 to prevent the escape of a liquid therethrough when the lidis in operative position. The outlet-opening 8 is also arranged in thelower wall 5 and is preferably formed in the cap 9, being so arranged asto discharge the disinfectant liquid in small quantities into the mainreceptacle. In order to control this discharge, I provide thedischarge-opening with a valve 11, which usually consists of a screw orplug having a lengthwise groove 12, which is made slightly tapering, sothat the quantity of liquid discharged can be controlled or entirelyshut off by moving the plug or screw endwise. It is thus apparent thatthe only openings required in the shell are the inlet-opening and thevent-opening,

the chamber 6 being otherwise hermetically sealed.

As seen in the drawings, the outer and inner walls 4 and 5 are formed ofsheet-metal plates dished in the same direction -and each having acentral opening 'aline'd with the other, the edges of the metal platessurrounding the central openings being crimped or otherwise securedtogether to form a watertight joint at this junction, the edge of theouter plate surrounding its opening being preferably turned downwardlyand crimped over upon a similarly downwardly-turned edge of the lowerplate 5. The upper plate 4 is arranged in the form of a flat invertedcone with the opening 3 at the apex and the outer or marginal edge ofsaid outer plate or wall 4 is turned downwardly and provided with a head13 at its extreme edge. Theinner plate 5 is also formed of sheet metal,which is pressed or otherwise made into the form of a cup constitutingthe receptacle proper for the disinfectant liquid, while the upper wallforms a cover for the chamber 6. The outer marginal edge of the innerplate 5 is also bent downwardly and outwardly and crimped upon the bead13 in such manner as to form a water-tight joint at the junction. Theouter edges of the plates 4 and 5 being turned downwardly, as described,preferably lie in close contact with each other for forming a flange 14and a groove 15 between the flange 14 and the body of the inner wall orplate. This double flange serves to reinforce and strengthen the shellat this point, which is the point of support for the top or shell uponthe main receptacle, the grooves 15 serving to receive the upper edgesof the side walls of said main receptacle and also hold the top or shellfrom lateral displacement.

In the operation of my invention when it is desired to fill the chamber6 with the liquid disinfectant the shell is inverted, and the cap orclosure 9 is then removed by unscrewing the same, which at the same timeremoves the valve 11, whereupon the liquid may be poured through theinlet-opening 7 in any desired manner. The cap is then replaced inposition, and the cover or hollow top is then placed upon the cuspidor,the valve 11 being previously adjusted to permit the disinfectant liquidto percolate or drip slowly from the chamber 6 into the main receptacle.

The operation of my invention will now be readily understood uponreference to the foregoing description and the accompanying drawings,and it will be noted that some change may be made in the detailconstruction and arrangement of the parts without departing from thespirit thereof. Therefore I do not limit myself to the desired form andcombination shown and described.

Having thus described inyinvention, what I claim, and desire to secureby Letters Patent, is-

1. Acap or cover for cuspidors comprising two sheet-metal plates dishedin the same direction and having alined central openings, the edges ofone of the plates surrounding the central opening being turned over andupon the like edges of the other plate and the outer edges of bothplates being in contact and turned outwardly and downwardly to form areinforced annular flange for the purpose described.

2. A cuspidor having a removable cover, said cover comprising two platesdished in the same direction, and having central alined openings,bothplates inclining upwardly from their central openings, the inner edgesof the upper plate being turned under the inner edge of the lower plateand secured thereto to hermetically seal the joint and the outer edgesof the plates being in contact and secured to each other to form a tightjoint.

3. A cap or cover for cuspidors comprising a hollow shell havingdish-shaped lower and upper walls and a central opening and providedwith a chamber surrounding the central opening, the lower wall having aninletopening, a removable bushing fitting in the inlet-opening andprovided with a dischargeopening, and a plug movable endwise in thedischarge-opening and provided with a tapering lengthwise passage forthe purpose described.

4. A cap or cover for cuspidors consisting of lower and upper plateseach formed of a single piece of metal and dished in the same direction,said plates having central alined openings and having their inner edgespermanently secured together to form a hermeticallytight joint, theouter edges of said plates being in contact and turned outwardly anddownwardly to form a depending annular flange and the portions of theplates between their inner and outer edges being separated to form achamber surrounding the central opening, and a valve in the lower wall.

5. In a cuspidor, a cap or cover consisting of a hollow shell having acentral opening and a chamber surrounding the opening, the lower Wallhaving a vent near its junction with the outer edge of the upper walland connecting said chamber with the interior of the cuspidor, aremovable bushing inserted through the lower wall near the centralopening, and a valve movable in the bushing for the purpose set forth.

In witness whereof I have hereunto set my hand this 8th day of April,1902.

CHARLES A. PAYNE.
